...d meal size, and enhanced satiety. These findings shed new light on the mechanisms of food intake during individual meals and provide strong evidence for a hypothalamic action of leptin in modulating satiety signaling. TITLE: Leptin Action in the Forebrain Regulates the Hindbrain Response to Satiety Si...... 1,000 different structures. These structures will shed light on how proteins function in many life processes and could lead to targets for the development of new medicines.

Ordovas, director of the Nutrition and Genomics Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University uncovered two variants in the perilipin gene that influence bod...Ingestion of afterbirth appears to promote maternal behavior in mammals
... His discovery led to a series of studies that shed light on the way in which POEF modulates how opioids inhibit nociceptive processing in the nervous system -- processing in specific areas of the brain that recognize certain kinds of pain. Kristal says this research may lead to novel ways of t...Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

... key aspect of its function. This discovery should shed light on both normal embryonic development and the development of cancer. In the paper, Sergei Sokol and colleagues, from Harvard Medical School, show that Dishevelled (Dsh) is constantly shuttling between the nucleus and the cytoplasm, owing to its ...Studies reveal methods viruses use to sidestep immune system

The findings shed light on how HCV disrupts a separate immune pathway in infected liver cells, again by unleashing the NS3/4A protease to cleave another protein essential to triggering immune defenses.

...of genomes. In addition, many of the organisms can shed light on human disease. For instance, the skate (related to many species of shark and cartilaginous fish) was chosen because it belongs to the first group of primitive vertebrates that developed jaws, an important step in vertebrate evolution.
